After 15yrs, the ol’ girl is finally getting some boost! I picked up a p1-sc2 with an old cast aluminum procharger 3 core intercooler and a power pipe. It has a 3.9 pulley. l Already have bbk long tubes with a bbk catted x pipe, straight through exhaust, c&l plenum, and 78mm TB, the internals are stock. It’ll have an aviator fuel pump with cobra 39# injectors and i have a BAP laying around if I need it. I’m getting close to dyno day and I’m wondering if I should swap in a smaller pulley before I have it tuned. Of all the info I’ve found on the p1sc2, which isn’t much, it seems to have a reputation for building boost lower in the rpms than the p1sc1. I assume that means a little more boost on top, too. What do you think? Play it safe, keep the 3.9? A 3.85 probably wont’t be a huge jump but is it worth it? Should I skip to 3.7? Thoughts? Thanks in advance.
